' COLOR-CARTRIDGE.

Specification of Letters Patent.

Application filed May 27, 1913, Serial No. 770,247. Renewed March 1, 1915. Serial No. 11,325.

To all whom it may concern:

Be it known that I, AUeUsr E. NIENSTADT, a citizen of the United States, residing at New York, in the county. of New York and State of New York,have invented certain new and useful Improvements in Color- Cartridges, of which the following is a specification.

My invention relates to a coloring cartridge for use in supplying ink-wells, reservoirs of fountain pens, stylographic pens and ink pencils, and for distributing laundry blue and the like.

One of the objects of the invention is to provide a cartridge which will supply the maximum amount of color.

A further object of the invention is to provide a cartridge which may be used in various forms and shapes, to permit of its being employed in conjunction with a fountain pen or an ink-well, or as a laundry blue distributer, with equal facility.

A still further object of my invention is the provision of a cartridge which is simple, clean, convenient and economical, and in which the nucleus or body portion will not disintegrate to form pulp or like substance.

To the accomplishment of the recited objects and others cofirdinate therewith, the preferred embodiment of my invention resides in that construction and arrangement of'parts hereinafter described, illustrated in the accompanying drawings, and embraced within the scope of the appended claims.

In said drawings, Figure 1 is an elevation of a piece of string previous to its being saturated with the coloring material. Fig. 2 is a similar view of the string after it has been saturated. Fig. 3 is a transverse sectional view taken along lines 33 of Fig. 2. Fig. 4 is a perspective view illustrating one of the forms into which the cartridge may be arranged, and Fig. 5 is a similar view of another form.

In the drawings, the numeral 1 designates a piece of string or cord of any desired length and composed of loosely twisted fibers. This string is immersed in any suitable coloring fluid and allowed to remain a time sufiicient to permit the fluid to thoroughly permeate and saturate all of the fibers. Subsequently, the string is removed from the bath and allowed to dry whereupon it is cut into short lengths of any desired longitudinal extents, as exhibited in the drawings. Manifestly, this method of forming the cartridges may be reversedthat is to sa v-the string may be initially cut to form a plurality of shorter strings which can then be subjected to the coloring treatment. It will also appear obvious that a wick or any other equivalent device involving a plurality of loosely arranged fibers will act in the same capacity as a nucleus.

As will be seen upon inspection of Figs. 2 and'ii, the coloring matter 2 adheres to the exterior portion as well as permeates the innermost interstices of the fibers, and by reason of the relatively large amount of color carried by the string, it will appear evident that when combined with water the maximum quantity of coloring fluid will be supplied. YVhen dry the color imparts a certain stiffness and rigidity to the fibers which maintains them straight or distended so that they may be readily inserted into a fountain pen or other small reservoir. At the same time this stiflness will not interfere with the flexibility of the cartridge. As shown in Fig. 4, the cartridge may be tied in a knot, as 3, and thus be easily accommodated by any ink-well or the like. Or, as illustrated in Fig. 5, the cartridge may be made in the form of a loop 4: with its extremities stuck or otherwise fastened, as at 5, to a holder 6. This device may be used as a laundry blue distributor.

Another important advantage possessed by my invention is that the fibers will not disintegrate and form a pulp which will clog or injure a fountain pen.

It should be understood that in its broader aspect the invention comprehends the employment not only of the various means described, but of equivalent means for per forming the recited functions. -While the arrangement shown is thought at the present time to be preferable, it is desired to reserve the right to efiect such modifications and variations thereof as may come fairly Within the scope of the appended claims.

What is claimed, is 2- 1. A color cartridge in the form of a string composed of a multiplicity of loosely arranged threads saturated and coated with readily soluble coloring matter.

2. A color cartridge in the form of a flexible string composed of a multiplicity of loosely arranged flexible strands saturated with a readily soluble coating mate-' readily soluble coloring matter, and having inherent rigidity to retain its distended condition.

4. A color cartridge in the form of a string composed of a multiplicity of longitudinally arranged strands saturated With and rendered stiff by a readily soluble coloring material.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

5. A color cartridge in the form of a string composed of a multiplicity of longitudinally arranged strands saturated With and rendered stiff by a readily soluble coloring material, and a holder to Which said string is attached and beyond which it pro jects.

In testimony whereof I affix my signature in presence of tWo Witnesses.
